Interplay between Superconductivity and Altermagnetism in Disordered Materials and Heterostructures
Rodrigo de las Heras, Tim Kokkeler, Stefan IliÄ +2
We study the interplay between superconductivity and altermagnetism in disordered systems using recently derived quantum kinetic transport equations. Starting from this framework,…
Spin-split superconductivity in spin-orbit coupled hybrid nanowires with ferromagnetic barriers
J. Zhao, A. Mazanik, D. Razmadze +4
We report transport studies of hybrid Josephson junctions based on semiconducting InAs nanowires with fully overlapping epitaxial ferromagnetic insulator EuS and superconducting Al…
Spin-galvanic response to non-equilibrium spin injection in superconductors with spin-orbit coupling
I. V. Tokatly, Y. Lu, F. S. Bergeret
We show that nonequilibrium spin injection into a superconductor can generate an anomalous supercurrent or induce a phase gradient, even for spin voltages below the superconducting…
Fluxoid solitons in superconducting tapered tubes and bottlenecks
Tim Kokkeler, Mateo Uldemolins, Francisco Lobo +3
A thin-walled tubular superconductor develops a quantized fluxoid in the presence of an axial magnetic field. The fluxoid corresponds to the number of phase windings of the superco…
Nonequilibrium spin-splitter effect in altermagnet superconductor hybrids
Tim Kokkeler, Tero T. Heikkilä, F. Sebastian Bergeret
We study the nonequilibrium spin-splitter effect in superconducting altermagnets and superconductor altermagnet hybrids by computing the alternating spin current and edge the spin…
Weak-anti-localization-to-spin-dependent scattering at a proximity-magnetized heavy metal interface
Hisakazu Matsuki, Guang Yang, Jiahui Xu +9
A change in a materials electrical resistance with magnetic field (magnetoresistance) results from quantum interference effects and, or spin-dependent transport, depending on mater…
